This Bulova men’s watch from the Maquina collection offers daringly avant-garde design. The watch features a 40mm black-tone stainless steel case with a curved sapphire crystal, a black bezel, and a black-tone stainless steel bracelet with a push-button deployant closure. The rainbow-colored patterned dial has black hands and silver-tone markers with luminescent fill and a central aperture revealing the inner workings of the 21-jewel automatic skeletonized movement, also visible through a transparent case back, which has a 42-hour power reserve. With its mechanical heart and unrivaled modern form, this Bulova men’s timepiece offers a uniquely individual expression of style.
